Coverage of the Mitsubishi Ki-46, a twin-engine reconnaissance aircraft used by the Imperial Japanese Army Air Force in World War II. Its Army Shiki designation was Type 100 Command Reconnaissance Aircraft; the Allied nickname was “Dinah." In 1944-45, during the last days of the war, it was modified as a high-altitude interceptor, with two 20mm cannons in the nose and one 37mm cannon in an "upwards-and-forwards" position (almost like the Luftwaffe's Schräge Musik night fighter cannon emplacements) for fighting USAAF B-29 Superfortresses over the metropolitan Japanese islands.
